摘　　要：通过岩石热解、饱和烃色谱-质谱、镜质体反射率等分析测试,对辽西牛营子盆地辽凌地1井侏罗系北票组烃源岩的有机质丰度、类型及成熟度进行了详细分析,综合评价了其生烃潜力.研究结果表明,侏罗系北票组有机碳含量分布在0.75%~37.9%,平均值为11.68%,有机质类型为Ⅲ型和Ⅱ_(2)型,镜质体反射率Ro主要分布于0.57%~0.62%之间,平均为0.60%,属于低成熟演化阶段.综合评价认为,牛营子盆地侏罗系北票组具有一定的生烃潜力.Through analysis of rock pyrolysis,saturated hydrocarbon gas chromatography-mass spectrometry and vitrinite reflectance(Ro),the paper studies the abundance,types and maturity of organic matters in the source rocks of Jurassic Beipiao Formation from LLD1 well of Niuyingzi Basin in western Liaoning,and comprehensively evaluates the hydrocarbon generation potential.The results show the TOC is 0.75%-37.9%,averagely 11.68%,with the III-and II_(2)-type of organic matters.The Rovalues mainly range from 0.57%to 0.62%,averagely 0.60%,belonging to the low maturity stage.From the above,it is concluded that the Jurassic Beipiao Formation in Niuyingzi Basin has certain hydrocarbon generation potential.
